To sdram it may concern:

Be it known that I, JOHN FITZGERALD, a citizen of the United States, residing at Newark. in the county of Essex and State of New Jerseyhave invented certain new and useful Im ri-twenients in Scissors-Sharpeners; and I do ereby' declare the following to be a full, clear. and exact description of tlie'inve'ntion,

' such s ill enable others skilled in the 'art to whichiit appertains to'niake'and use the sainereference being had to the accompany ing iran-ings, and to figures 'of reference marketl Iheremr.-which forni a part of this specication. invention relates to a device for sharpening shears and similar articles, and consists of a block to be gras'ied by the hand and to be slid back and fort along the cutting erige of a blade, and is designed,v particuli-ary, for such blades as shear-blades, where one of the cutting edges Ais perpendiculr and the other chanifered or beveled. The invention consists inore particularly in supplying a Sharpener that hasa guiding means for holding the blade at the proper angle- Io the grinding surface to cause a pro :r preparation of the cutting edge.

he invention is illustrated in the accompany-ing drawing, in which A Fig-are 1 is a perspective yiew showing the sharp-ener as it is applied to a blade of a pair of shears. and Fig. 2 is an end View of the Sharpener with the blade in section.

sliarpener consists of a suitable block 10 which may be made of any suitable ina-terial. but is preferably made of'wood. and it. hasiLs-erted therein a grinding bar 11 which is 'pre-vided, on its to surface, with an abrasive ainforination being preferably cut with.

iileteeth, although any substitute such as einer? may be installed. The blo'ck 10 is Specification of Letters Yatent. Application 'led Gctober 24. 1907. No. 398,859.

ba'r- 1-1. one side of the recess having a perpendicular wall12, the other wall of the recess being inclined as at 13. at an angle. to bring the blade l5 properly onto the grinding surface so thatl when it is slid back and forth alongl the grinding bar, the blade will be inaintaiiieti at the saine angle to the grinding surface. and the blade is sharpened the same from one end to the other- To prevent the accidental displacement of the blade from its position- I may undercut. as at l. the lower part of the perpendicular wallv I2 of the recess of the block.

be operate( by anybo since the angular sharpening necessary on the scissors or shears is insured. A

Having thus described in v invention` what. I claim is A sharpener for shears comprising a block having a grinding bar longitudinallyr above the grindingbar, one wall of the rece being perpendicu ar and having a slightly undercut portion adjacent to the grinding bar, the other wall of the recess being iiiclined at an angle to the grinding bar and being approximately parallel with the undercut Eortion of the perpendicular wall, whereby a l lade inserted in the Sharpener is maintained at a vproper 'angle to the grinding bar, and can only be withdrawn in a direction substantially parallel to the inclinedn'all.

In testimony, that I claim the foregoing, I lhave. hereunto set my hand this 21st day of October 1907. l JOHN FITZGERALD.
